[New Algorithms for Evaluation Myocardial Function According to Echocardiography].

The article is devoted to the novel methodological approach to assessment of function of the myocardium and the left ventricle as a whole with the help of modern methods of processing ultrasound images obtained by echocardiography. It contains presentation of theoretical prerequisites for elaboration of a new direction, as well as mathematical computations basing on which quantitative parameters for assessment of myocardial function and blood flows within chambers of the heart were obtained. The fundamental principle in assessing these parameters was the use of the phase structure of the cardiac cycle.
